140Chapter D - User's Manualthat it is a CD-ROM drive). Information on the various CD-ROM drives which can be usedcan be obtained directly from adaptec.D.6.2 Example: Using corelSCSI for the NEC CD-ROMWhen using the corelSCSI software, the installation is carried out by a program (install), sothat the changes in the files CONFIG.SYS and AUTOEXEC.BAT mentioned below are, to alarge extent, made automatically. Under corelSCSI the SCSI/FAST-SCSI channels of the GDTcontroller are available as independent host adapters. The important lines in both files areprinted bold.CONFIG.SYSdevice=c:\windows\himem.sysdevice=gdtx000.exefiles=30buffers=30stacks=9,256dos=high,umbshell=\COMMAND.COM /E:512 /Pdevice=\dos\setver.exedevice=\gdt\gdtaspi.exedevice=c:\corel\cuni_asp.sys /ID:6 /HAN:0 /N:1 /D:MSCD000lastdrive=hAUTOEXEC.BATpath=c:\;c:\dos;c:\gdt;c:\aspi;prompt $P -$Gc:\corel\corelcdx /M:8 /D:MSCD000The first line following the HIMEM.SYS command of the CONFIG.SYS file loads theGDTX000.EXE. The next line loads the GDT ASPI Manager GDTASPI.EXE. Next, the corelASPI Module for the NEC CD-ROM drive is loaded. The parameter "/D:MSCD000" hasnothing to do with a drive name, it only serves as a recognition information for COREL CDX.As mentioned before, it is our objective to be able to access the CD-ROM drive with a drivename (i.e. E). Naturally, this drive name has to be "free", and there have to be enough drivenames available. For example, the command LASTDRIVE=H would al low to use drivenames from A to H under DOS. In the AUTOEXEC.BAT file, the corel translation programfor CD-ROMs, CORELCDX, is loaded. The parameter /D:MSCD000 set here has to be ident i-cal to the parameter set after the ASPI Module in the CONFIG.SYS file. After a warm rebootwhich serves to activate the changes made in the CONFIG.SYS and AUTO EXEC.BAT files,the NEC CD-ROM drive can be accessed as drive E (in our example there are two SCSI harddisks in the PCI computer, and under MS-DOS they are accessed as C and D). Drive E canbe accessed under Windows, too, now (the Icon next to "E" indicates that it is a CD-ROMdrive). Information on the various CD-ROM drives which can be used can be obtained d i-rectly from Corel.D.7 Using a DAT drive under MS-DOS with Sytos PlusSytos Plus from the company Sytron is a professional backup manager used in many systeminstallations for backup purposes. Similarly to our last example, Sytos Plus accesses NotDirect Access Devices through the GDT ASPI Manager.
